React Scripts Syntax Error on Build

[tairemad]

Having an issue doing a deploy to prod.

*netlify site name: naughty-ritchie-3030d6.netlify.app

This is a Create React App that is failing on build to production. Also just changed build image from Ubuntu Xenial to the default Ubuntu Focal 20.04

Here is the logs. If I build this locally I am not coming across this issue.

Hey @tairemad,

This appears to be some issue with Jest: https://github.com/facebook/jest/issues/6933. It looks like from time to time, it randomly reports some weird syntax errors.

[tairemad]

I did have a test error that I fixed but the logs are still showing the same error on build…create react app hides all the babel and config files. I wonder if I expose them and try to update a config will this really solve the issue?

Can’t say. That’s a possibility you’d have to explore. Take a backup of your project and feel free to continue the investigation.

I ended up fixing the test and updating node and npm version on my site and this no longer the issue I am having…now its a new timeout issue
